Just for reference, C5, C7, C17 and C18 are typically 250pf mica caps (red, green, brown dots) and C12 looks like a tone conditioner .001mfd to .01mfd selected to your taste. Tube layout looks good, you can pretty much verify that from the schematic vs wiring (eg. The oscillator coil will be connected to the 12SA7 socket). Looks like all you need is a running oscillator. If you have access to an rf generator you should be able to send the IF (455 kHz?) into the antenna and see the voltage at the volume control change with signal strength.
